SANDING DEVICE.

Patented Feb. 2, 1915.

Application filed October 9, 1912. Serial No. 724,724.

To all whom it may concern:

Be it known that I, l/VALTER V. TURNER, a citizen of the United States, residing at Edgewood, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Sanding Devices, of which the following is a specification.

This invention relates to sanding devices, and more particularly to a valve mechanism for controlling the supply of sand to railway rails to assist in stopping and starting trains.

The principal object of myinvention is to provide an improved sand valve mechanism in connection with a brake valve device which is adapted to be operated at will in anv position of the brake valve handle.

In the accompanying drawing; Figure 1 is a sectional view of an engineers brake valve, showing the improved sand valve mechanism applied thereto and Fig. 2 a plan view thereof.

The brake valve may be of the usual construction comprising a casing 1 having a valve chamber 2 containing a. rotary valve 3 adapted to be operated by brake valve handle l, the valve chamber 2 containing fluid at main reservoir pressure.

According to my improvement, a sand valve casing 5 is screwed into a threaded aperture formed in the cylindrical side wall of the brake valve casing 1, so that an opening 6 from valve chamber 7 of the sand valve casing communicates with the brake valve chamber 2. WVithin the valve chamber 7 is mounted a valve 8 subject to the pressure of a spring 9 tending to maintain the valve 8 on its seat and said valve is adapted when opened to supply fluid from the brake valve chamber 2 to a pipe 10, the admission of fluid to which is adapted to effect the discharge of sand on the rails. The sand valve 8 is provided with a stem 11 which projects out radially through an aperture in the casing 5, so that by pressing the stem inwardly, the valve 8 may be lifted from its seat.

Pivotally mounted on a lug 12 carried by a brake valve casing 1 is a curved segment bar 13, so located that when the bar is pressed inwardly, the same will engage and force inwardly the valve stem 11. The end of the bar 13 opposite to the pivotal end is preferably supported on a lug 14c and said bar is of sufficient length to cover all operating positions of the brake valve handle from release position to emergency position. The brake valve handle a is pivoted to the stem 15 of the rotary valve 8 and is provided with a downwardly proecting arm 16 adapted, upon vertical movement of the brake valve handle 4 on its pivotal support, to engage with the bar 13 and press the same inwardly.

It will now be evident that in operation, the engineer can manipulate the brake valve handle in the usual manner to control the brakes and when it is desired to sand the rails, the engineer may, by pressing down on the brake valve handle in any position in which the handle may be, cause the valve stem 11 to be forced inwardly by the inward movement of the bar 13, so that the sand valve 8 is lifted from its seat to admit fluid under pressure to the sand pipe 10.

In addition to the usual operation of the sand valve by pressing down on the brake valve handle, the sand valve is adapted to be automatically operated upon movement to emergency application position, and for this purpose, the bar 13 is provided with a thickened end portion 17 adjacent to the emergency position, so that the movement of the brake valve handle 4 to emergency position causes the arm 16 to engage said thickened portion and thereby force the bar 13 inwardly without depressing the brake valve handle.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a brake valve device provided with an operating handle, of a sanding mechanism and means adapted to be operated by said handle in any position of the handle for effecting the operation of said sanding mechanism.

2. The combination with a brake valve device provided with a handle for operating the brake valve upon movement in one plane, of a sanding mechanism and means adapted to be operated upon movement of the handle in another plane for effecting the operation of said sanding mechanism.
